Application filed October 18,1905. Serial No. 283.348.

To all whom it 707/113./ concern:

Be it known that I, VICTOR KoBLER-STAU- DER, a citizen of theConfederation of Switzerland, residing in the house Villa Wyssenstein,at Rohrschach, Switzerland, have invented a new and usefulEmbroidering-Vlachine, of which the following is a specification.

In embroidering-machines of the kind invented by Heilmann (see BritishPatent- No. 5,788 of 1829) it was for the production of open or piercedwork hitherto necessary to position by hand the bore-points to producethe holes during a stitch period of the machine and to withdraw by handthese tools with their carriers, so as to permit the needles to performtheir operation during a number of following stitch periods, eitheralone or in combination with the known feston devices. The positioningand withdrawing of the borepoint carriers had to be effected mostly fromone end of tlie machine, so that the operator was either obliged to moveaway from and again back to his pattern or to employ an assistant forthe said purpose. This means, however, a great loss of time, and besidesthis there was also a great drawback in that the long machine partsemployed in the positioning and withdrawing devices were subjected totorsions.

My invention relates to improvements in embroidering-machines of theclass mentioned above, whereby the production of the machine isconsiderably increased, as the operator is now enabled to remain at hisplace before the pattern and yet to actuate in an easy and comfortablemanner and without any assistance the positioning and withdrawingdevices, while the latter are so much improved upon as to maintain theirexactitude for a much longer time than hitherto, so that the nicety ofthe open or pierced work is guaranteed.

The said improvements will be hereinafter described and explained withreference to the accompanying drawings, in which- Figure 1 is aleft-side view of a part of a known Heilmanns embroidering-machine towhich the new positioning and withdrawing devices, according to myinvention, are applied, intermediate parts being omitted for want ofspace. Fig. 2 is partly a plan and partly a horizontal section throughthe line C Din Fig. 1. Figs. 3 and 3a are parts of a ver-`broidering-machine comprises two machineframes 1 1, Figs. 8 and 3-a onthe left and on the right and a very long beam (not shown) connectingthe upper ends of central vertical arms of these machine-frames, avertical embroidering-frame suspended from the long beam and balanced bycounterweights and adapted to be shifted in its vertical plane, and twolong carriages, one ony the front and one on the rear. The operatorsitting on the one side-for example, on the left beside the leftmachine-frame 1-and before his pattern adjusts the embroidering-framefor each stitch by means of the known pantograph. By depressing the oneof his two known-pedals (not shown in the drawings) he engages adrivingwheel inthe gearing of, say, the front carriage andsimultaneously opens the rear needle-tongs and closes the frontneedle-tongs. Then he turns his hand-crank in the one direction to moveby means of the drivinggearwheel the front carriage to the front awayfrom the embroidering-frame, so that all the needles secured in thefront needle-tongs draw the threads through the fabric, (marked S inFig. 5.) embroidering-frame for the following` stitch and turns hishand-crank in the opposite direction to move the front carriage to therear until it stops before the fabric. Afterward he depresses his otherpedal to engage the driving gear-wheel in the gearing of the rearcarriage and to simultaneously open the front needle-tongs and to closethe rear needletongs. Thereupon he turns his hand-crank to move the rearcarriage to the rear, so-that the rear yneedles draw the threads throughthe fabric. Now the operator adjusts the embroidering-frame for the nextfollowing stitch and turns his hand-crank in the opposite direction tomove the rear carriage to the front until it stops before the fabric.

Next the operator adjuststhe IOO The front carriage (shown at Figs. 3and 3a) comprises a very long tube 64 and two side parts 29 29, Fig. 1,from which the ends of the former are suspended and on which they arefastened. The two side parts 29 29 are each formed at both ends intoforks 32 32 for carrying the aXles 33 33 of two wheels 30 and 3 1,respectively. The latter are arranged to roll on four rails 34 34,secured in the machine-frame, two on the front and two on the rear (notshown in Fig. 1, but in Figs. 4 and 5) of the embroidering-frame. I donot show the gear for driving the two carriages, as it is old and formsno part of my invention.

The long tube 64 of each carriage is provided with a plurality of upperand lower arms 52 52 (of which only two, respectively, are shown atFigs. 3 and 3aL for want of space) and two needle-bars 52 52, one aboveand one below. I have not shown the two needle mechanisms on the twoneedle-bars 52 52 as they form no part of my invention. Theembroidering-frame is arranged to receive two pieces of fabric S, oneabove the other, which are stretched in the frame and periodically fedin any known manner.

All the parts described so far are old; but the followingparts are newand form my invention.

On the middle part of the left machineframe 1 within easy reach of theoperator a cross-piece v2 is fastened, which serves as a bearing for theshaft 58 of a hand-lever 3 and is made in one piece with a bow 2. Thisbow is provided with a plurality of holes 57 57 and in its middle with anotch 59, Fig. 2. Twoadjustable stops 11 11 may be put in any of theholes 57 57 for determining the stroke of the hand-lever 3, a lug 60 onthe latter, Fig. 3, being adapted to strike against either stop 11. Aspring-pressed bolt 61, guided in this lug 60, is adapted to engage inthe notch 59 of the bow 2/ for holding the hand-lever 3 in its middleposition. Thereby the operator is enabled to quickly return thehand-lever 3 from either eXtreme position to its middle position. On theinternal end of the shaft 58 is fastened a double cam 13, whichtherefore partakes in the motion of the hand-lever 3 and carries asecond cam 14, that will be referred to later on. The handlever 3 isprovided with a short arm at right angles to it, which carries a pin 6.This pin 6 en ages in the horizontal slot 5, of a rod 4, whic isivotally connected with two levers 7 and 8 a ove and below. The upperlever 7 is fastened on a horizontal shaft 10, which passes through themachine from the one side frame 1, Fig. 3, to the other side vframe 1,Fig. 3a, and carries at the right end a similar lever 7. In a similarmanner the lower lever 8 is fastened on a horizontal shaft 9, whichpasses from the one side frame 1 to the other side frame 1 and carriesat the other end a similar lever 8.4 The levers 7 and 8 on the right arepivotally connected with each other by means of a rod 4, which has thesame shape as the left rod 4. yEvidently on moving the hand-lever 3 fromits middle position to either sidesay to the front, as in Fig. 4i thetwo rods 4 4, with the upper levers 77 and the lower levers 8 8, will besimultaneously raised. Each rod 4 has a pin 18 fastened on itintermediate its upper end and its slot 5. This pin 18 is adapted toslide on the edges of two arms 19 19, which are fastened on a shaft 2Oat a certain angle to each other, as shown in Figs. 3 and 3a. The shaftl20 on either machine side is mounted to turn in a bearing 12 and carriesat its rear end a lever 21 with a pin 62. On each machine side ahorizontal shaft 24 is mounted to rock in suitable bearings 63 63 andhas fastened on it a slotted lever 22 in contact with the one bearing 63and two levers 26 at each end, which carry two rollers 55 and 56,respectively. Springs of any suitable known construction (not shown)serve for returning the two horizontal shafts 24 24 into their middlepositions. `(Shown at Figs. 3 and 3a.) The pins 62 62 of the two levers21 21 engage inthe slots of the two slotted levers 22 22. When the twopins 18 18 on the two rods 4 4 are moved upward by turning thehand-lever 3 to the frontdthat is, to the right in Fig. 4-these two pins18 18 will depress the two upper arms 19 19 and so turn the two shafts24 24 by means of the parts 20, 21, 62, and 22 as to bring the two inswith the two lower rollers 56 56 into a orizon-tal position. The arms 1919 are provided with adjustable screws 19a 19a, (see Figs. 1 and 3,)which are adapted to alternately bear on the frames 1 1. When thehandle-lever 3 is moved in either direction, the pins 18 18 will slideon the upper or lower arms 19 19 (as the case may be) and depress them,so that these arms will now be locked, since their adjustable screws 19a19iL bear on the frames 1 1. Thereby also the shaft 24 24 will beprevented fromy moving. The adjusting-screws have also the purpose toprevent the double lever 19 from moving of its own accord, a certainroom for motion being left between the arms of the lever 19 and theframe 1, as shown in the drawings. By turning the hand-lever 3 to therear v(to the left in Fig. 1) the two pins 18 18 on the two rods 4 4will be moved downward and depress the two lower arms 19 19, whereby thetwo upper rollers 55 55 will be brought into a horizontal position.

On the two upper projections of the long tube 64 of the front carriage Aabove the two side parts 29 29 are fastened two brackets 27 27, in eachof which two horizontal superposed shafts 36 and 36 are mounted to turn.The two upper shafts 36 36, Figs. 3 and 3a, have fastened on them twocams 35 35 at their external ends and two levers 37 37 at their internalends. The two upper cams 35 ICG 35 are adapted to strike the two upperrollers 55 55, mentioned above, on the latter being brought into theirhorizontal position, and thereby into the paths of these cams. The twolower shafts 36 36 have fastened on them two cams 35 35 at theirexternal ends tion the wooden pads 50 50 during their opand two levers39 39 at their internal ends. The two lower cams 35 35 are adapted tostrike the two lower rollers 56 56, mentioned above, on the latter beingbrought into their horizontal position in the manner explained before.On the two needle-bars 52 52, already referred to above, are fastenedseveral two-armed supports 47 47, which are shown in Fig. 1, but arecovered by other parts 49 49 in Figs. 3 and 3a. The upper ends of thetwo arms of each support 47 are provided with pins 48 and 53,respectively. On the pins 48 48 in the arms farther offl from theembroidering-frame bent levers 49 49 are mounted to turn, which carry awooden pad 50. The two ends of eachpad 50 are rigidly connected with twometal arms 51 51, the free ends of which are nearer the axis of .thepins 48 than the wooden pads 50. The free ends of the four arms 51 51 onthe two pads 50 50 above and below are pivotally connected with eachother by means of two cranked rods 44 44 and four pins 43 43. (See Figs.1, 3, 3a, and 5.) Fastened on these two cranked rods 44 44 near theirvupper ends are two cast pieces 41 41, carrying two adjustable arms 3838, which latter are pivotally connected with two upper levers 37 37,already mentioned above. The two upper rollers 55 55, on beingsimultaneously moved into their horizontal position from the handlever 3in the manner described above, can strike and simultaneously turn thetwo upper cams 35 35 and by the two shafts 36 36 also the two upperlevers 37 37 in either direction through an angle of one hundred andeighty degrees, so that the two cranked rods 44 44 will be moved bytheir adjustable arms 38 38 to simultaneously turn the two pads 50 50around the pins 48 48. As the length of the two levers 37 37 is equal tothe distance of the pins 43 43 from the axis of the pins 48 48 itfollows that the two wooden pads 50 50 will also be moved through anangle of one hundred and eighty degrees. On the pins 53 53 in the armsof the several supports 47 47 nearer the embroidering-frame levers 54 54are mounted to turn, which carry aborepoint carrier 46. The latter isprovided with a series of bore-points 65 of any cross-section, as usual,and of a uniform length. The two wooden pads 5() 50 of either carriageare provided with holes in which the bore-points 65 65 on the bore-pointcarriers 46 of the other carriage can engage. (See Fig. 5.) The levers54 54 are each provided with a lug which is adapted to bear against thevertical face of the support 47 nearer the embroidering-frame forholding the bore-points 65 65 in their horizontal position during theiroperation. In a similar manner the bent levers 49 49 are provided withlugs (see Figs. 1 and 5) adapted to rest on those upper ends of thecorresponding supports 47 47 which .are nearer the embroidering-frame,so as to posieration. The two ends of each bore-point carrier 46 arerigidly connected with two arms 45 45, the free ends of which are at thesame distance from the axis of the pins 53 as the pins 43 on the arms 5151 of the wooden pads 50 50 are from the axis of the pins 48 48. Thecorresponding arms 45 45 on the two bore-point carriers 46 46 above andbelow are pivotally connected with each other by means of four pins 4343 and two cranked rods 44 44, which resemble those 44 44 mentionedabove. Fastened on these two cranked rods 44 44 are two cast pieces 4141, carrying two adjustable arms 40 40, which latter are pivotallyconnected with the two levers 39 39, already mentioned above. rl`he twolower cams 35 35 are adapted to strike the two lower ollers 56 56 on thelatter being brought into their path and to be thereby moved for turningthe bore-point carriers 46 46 in the corresponding direction through anangle of one hundred and eightydegrees. It will be seen that both thewooden pads 50 50 and the bore-point carriers 46 46 may be thrown backover the needle mechanisms to permit the latter to perform their work.

On the rear carriage B substantially the same parts and the samebore-point carriers and wooden pads are disposed as on the frontcarriage A; but there is a diference between the two carriages in thatwith the front carriage A the two lower cams 35 35 are arranged foractuating the two bore-point carriers 46 46, while with the rearcarriage B the two lower cams 35 35 are arranged for actuating the twowooden pads 50 50, and that with the front carriage A the two upper cams35 35 are arranged for actuating the two wooden pads 50 50, while thoseon the rear carriage B serve for actuating the two borepoint carriers 4646.

Either the bore-points 65 on the front carriage A or those 65 on therear carriage B may be used for piercing the fabric. In the former casethe hand-lever 3 is moved to the front forA bringing the two lowerrollers 56 56 into their horizontalv position, so that the bore-points65 65 of the front carriage and the wooden pads 50 50 of the rearcarriage may be positioned. In the latter case the hand-lever 3 is movedto the rear for bringing the two upper rollers 55 55 into theirhorizontal position, so that the bore-points 65 65 of the rear carriageand the wooden pads 50 50 of the front carriage may be positioned.

For the purpose of adjusting the depth to which the bore-points 65 65may engage in IOO ISO

the holes of the corresponding wooden pads 50 50, andtherebyidetermining the size of the holes to be bored in the fabric, thefollowing arrangement is made: The double cam 13, already mentionedabove, is so shaped that when the hand-lever 3 occupies its middleposition (shown at Fig. 1) the bearings 32 32 of the left wheels 30 30of the two carriages A and B are permitted to pass freely beneath thetwo cams 13 13. On turning, however` the hand-lever -3 through. asmall'angle to either side-the respective cam 13 will stop the bearing32 of the left wheel 30 if this bearing 32 strikes it. On turning thehand-lever 3 farther the cam 13 will stop the carriage a little later,so that the bore-points 65 are permitted to engage a little deeper inlarger holes in the fabric. The more the hand-lever 3 is turned thelarger will be the holes produced in the fabric. In the crosspiece 2 arefastened two pins 17 17, on which two locking-levers 16 16 can swing,while they are pressed upward by a spring 66, connecting theirverticalarms 15 15. These two arms 15 15 carry two rollers 15 15, which areadapted to bear against and to roll on the cam 14. The latter issoshaped as to hold the two locking-levers 16 16 in their normal position(shown at Fig. 1) as long as the hand-lever 3 occupies its middleposition. rlhe two locking-levers 16 16 are adapted to be alternatelydepressed by the projecting ends of the aXles 33 33 of the left wheels3() 30 of the two carriages and to lock them for stopping the respectivecarriage.

The mechanism described so far is operated as follows: According'to thedesired size of the holes to be bored in the two pieces of fabric S thetwo adjustable stops 11 11 are put in the corresponding holes 57 of thebow 2 to determine the stroke of the hand-lever 3, and thereby also thedepth to which the borepoints 65 65 of the one carriage may engage inthe holes of the wooden pads 50 50 of the other carriage. It is assumedthat the operator wishes to employ the bore-points 65 of the frontcarriage A for making the holes in the fabric. The operator sitting athis pattern performs his work in the usual manner, so that the needlespass from the one carriage through the pieces of fabric S to the othercarriage, and vice versa, to make the stitches. When the operatordesires to make holes in the fabric, he so stops his work that the frontcarriage A occupies its eX- treme position on the front, while the rearcarriage B is immediately behind the embroidering-frame. He nowdepresses the other pedal to disengage the driving-wheel from thegearing of the front carriage A and to engage it in the gearing of therear carriage B and turns his hand-crank in the respective direction tomove, by means of the driving-wheel, the rear carriage away from thepads 50 50 and to make.

the embroidering-frame to the rear. At this moment both carriages A andB will be on the external sides of therespective rollers 55 56 55 56 onthe front and on the rear of the embroidering-frame. The operatordepresses the first pedal to disconnect the driving-wheel from thegearing of the rear carriage B and to connect it with the gearing of thefront carriage A. Subsequently he turns the hand-lever 3, which iswithin his reach, to the front-that is, to the right in Fig. 4. Then thepin 6 on the short arm of the handlever 3 and engaging in the horizontalslot 5 of the front rod 4 will have raised the latter, and therebyturned all the four levers 7 8 upward by means of the two horizontalshafts 9 and 10 and the right rod 4. The two horizontal pins 13 18 onthe two rods 4 4 will have depressed the two upper arms 19 19, so

that by means of the two shafts 20 20, the two levers 21 21, the twopins 62 62, and the two slotted levers 22 22 the two horizontal shafts24 24 will be turned to bring the four lower rollers 56 56 into thepaths of the four lower arms 35 35. The cam 14 will have depressed thefront locking-lever 16 and raised the rear locking-lever 16 into theposition shown at Fig. 4. Now the operator turns his hand-crank to movethe front carriaOe A to the rear, so that the two lower cams 35 35 ofthis carriage striking the two front lower rollers 56 56 will be therebyturned through more than a right angle, whereupon the two bore-pointcarriers 46 46 of the front carriage A, having passed to the rear sideof their axes 53 53, will fall down into their other horizontal positionand turn the two lower cams 35 35 into their other extreme position.(Shown at Fig. 5.) In other words, the two bore-point carriers 46 46 onthe front carriage A are now positioned. On the front carriage A furtheradvancing the bearing 32 of its left wheel 30 will strike the front cam13 (see Fig. 4) and be thereby stopped in such a position that its knownvertical rod controlling the two needle mechanisms remains out of thereach of the front fork of the known two-armed forked lever, whichlatter is controlled from the two pedals. Therefore on the operatordepressing the other pedal to disconnect the drivingwheel from thegearing of the front carriage A and to engage it in the gearing of therear carriage B the front needle-tongs will remain closed and hold theneedles with the pendent threads. lt is to be noted that the needles inthe front needle-tongs will have touched the two pieces of fabric S andmay have pierced them to the adjusted depth or a part of the same. Nowthe operator turns his hand-crank to move the rear carriage B to thefront, so that the two lower cams 35 35 of this carriage striking thetwo rear lower rollers 56 56 will be thereby turned through more than aright angle, whereupon the two IOO IIO

wooden pads 50 will swing forward and be positioned. On the rearcarriage B further advancing the projecting pin 33 of its left wheel 30will depress the rear locking-lever 16 until it gets into the recess ofthe latter and becomes locked, since the spring 66 presses thelocking-lever 16 upward. Thereby the rear carriage B is stopped in sucha position from the embroidering-frame that its two wooden pads 50 50are in contact with the two pieces of work S, which means that the twowooden pads 50 50 may have pushed the two pieces of fabric S over theborepoints to the desired depth, so that the holes so produced in thefabric have the proper size. The parts on the rear carriage B whichcontrol the rear needle-tongs also remain out of the reach of the saidtwo-armed forked lever, so that neither the needle mech: anisms on thefront carriage A nor those on the rear carriage B will be in any wayinterfered with by depressing either of the two pedals. The two piecesof fabric S having been thus bored, the operator depresses the firstpedal to disconnect the driving-wheel from the gearing of the rearcarriage B and to engage it in the gearing' of the front carriage A,whereupon he turns his hand-crank to move the front carriage Ato thefront, during which motion, of course, the two lower cams 35 35 of thiscarriage will have struck the two front lower rollers 56 56 and beenthereby turned so that the two borepoint carriers 46 46 are swung backto their normal position. (Shown at Fig. 1.) Afterward the operatordepresses the other pedal to disconnect the driving-wheel from thegearing of the front carriage and to engage it in that of the rearcarriage, and then he returns the hand-lever 3 for a moment to itsmiddle position, so as to release the rear carriage B by lowering therear locking-lever 16. N eXt the operator turns his hand-crank to movethe rear carriage to the rear out of the reach of the rear locking-lever16, and at the same time he moves the hand-lever 3 to the front, so asto bring the two rear lower rollers 56 56 again into the paths of thetwo lower cams 35 35 on the rear carriage B, which cams are thereforeturned to swing back the two rear wooden pads 50 50 to their normalposition. Thereupon the operator depresses the first pedal to disconnectthe driving-wheel from the gearing of the rear carriage B and to engageit in that of the front carriage A. After adjusting theembroidering-frame for the following stitch by means of the pantographand the pattern the operator continues his usual work.

It is evident that the manner described of positioning and withdrawingthe bore-point carriers and the pads may be varied. The skilled operatormay find it convenient to move the hand-lever 3 and his hand-crank moreor less simultaneously to save time. He

need not move either carriage quite to the eXtreme external position;but he may move it just beyond the reach of the respective rollers or 56and turn the hand-lever 3, also turn his hand-crank and depress thepedals in a certain sequence to attain the same effect. I-Ie may preferto use the b0repoints of the rear carriage B instead of those of thefront carriage A for producing the holes in the fabric S, according tothe kind of work to be produced. In this case, of course, the hand-lever3 will require to be turned to the rear, so as to bring the two upperrollers 55 55 into the paths of the two upper cams 35 35 on bothcarriages A and B. The operator may also first position the two woodenpads 50 50 of the one carriage and afterward position the bore-pointcarriers 46 46 of the other carriage, so as to produce holes of thecorrect size.

The whole arrangement described above may be varied in many respectswithoutdeparting from the spirit of my invention.

What I claim as my invention, and desire to secure by Letters Patent,is-
